Enswnznn A.- W JEF- rinunce, as ctizenof the 'United States, re-

siding at oi'c'ester, in the county of 1V orcester and Commonwealth of' Massachusetts, have invented a new", and' useful ImprovementJnGas-Produces, of which the follow- ;ingis-,a specification, accompanied by ldraw'- ingsl forming ofthe same. y TheiobJectsfof my improvement are to secure ammore uniform distribution of coal through thechamber'; to level the upper surface of the fuel mass and prevent thecoalesc-l ing-or calring ofthe lfuel to prevent the for: mationhof pipesorJluesdue 'to the unequal-combustionofcOal, and to accomplish the-more2, perfect disintegration `of the coal v during the proce'ssLO;QQmbustion. 1 attain thesevobj ects bythe mechanism.illustrated in the accompanying draw-ings, in which--' Figure 1f is= a: side lelevation of algas` producer with the `lower portion,r;fro1n limmediately above the upper line of fuel, shown in vertical central-section; Fig. 2 is a horizontal section on alineapproximately level with the line of the poker.

Similar reference characters refer to similai' parts in the different figures.

Referring to the drawings, the gas producer chamber 1 with its upper portion inclosed within walls of a suitable refractory material, is supported upon posts 2 and comprises a lower water cooled section 3 extending downward into a rotatable ash pan 4 which is supported upon friction rolls 5, and which is rotated by any preferred means of rotation, not shown. A dome 6 with extending arms 7 is supported upon and yrotated by the ashpan and provides-a passage of entrance for the necessary blast of air and steam which is conducted into the bottom of the gas producer chamber 1 through the arms 7. The rotation ofthe dome 6 and ber 1.

ing through'the chamber 1 just below the',v

line of the fuel is a `rotatable water pipe forming a Water C001d POker 14, J'Ollrnaled" y' in hollow waterv cooled bearings 15 .-andlG heldin alinement in the walls of thecham.- One side of the poker 14 is connected with the hollow shaft 12 which is 'driven by the sprocket wheel 9' and through which the poker 14 is suppliedV with water.; The opposite end of the poker 14 is .connected with a hollow shaft 17 journaled in a bearing 18 supported upon the top of the lower waiter cooled sectionY 3 of the gasproducer chamber.'- The hollow shafts-12 and 17 loom.- m'unicate with the hollow poker 14 andv with the pipes 19 and 20 connected-with station@ ary hollow caps 21 and 22 inclosing the ends f:

of the shafts 12 and 17 form a water'circulatory system through the poker 14, l

The poker 14 is crank shaped as itfpasses through' the chamber 1 between the hollow bearings 15. and 16, and extends obliquelywI downi'vard'from the bearing 15 "'ahnost entirely across the chamber where the slant of poker 14 is sharply reversed at 23 extending upward until the end of the poker 14 is in alinement with the bearing 16. It is obvious that the rotation of the poker will cause a change in position of the angle at 23, and the inclined section of the poker revolving it around an axis coincident with the axes of the bearings 15 and 16. The slant of the poker 14 is so arranged in angular extent that when the angle 23 is in its highest position it will be preferably above the mass of fuel, as shown by the dotted lines 24 in A This revolution of the poker 14 is designed to accomplish the breaking up of the upper portion of fuel as it extends through the top of the fuel bed and is in contact with the coal when first introduced into the gas producer. The mass of fuel is carried against the revolving poker 14 by the rotation of the fuel due to the ash pan.

and mechanism connected therewith as above described, and the revolutiony of the poker 14 1s arranged to correspond with,

and accompany in direction, the rotation of' the fuel when the poker is passing through the fuel mass` This correspondence in di- `,and 16 from excess of heat.

rection is `shown by the'arrovvs 25 and 26, Fig. 2, which shows the direction ofthe fuel and the poker respectively.`

The slant of the poker 14 and the angle at 23 is designed when passing through the upper part of its revolution to level the 11p-- per surface of the fuel and when in the lower portion of its path to agitate the fuelI to a greater depth. The greatest agitation of the fuel will occur Where the poker is buried deepest, or at'the section 23 and as the fuel mass is rotated itwill become uniformly subjected to the agtating action of the poker. The bearings 15 and 16 for the 'revolving poker, as shown in -Fig. 2, are provided with a Water chamber 27 supplied with a Water current through the pipes 28' and 29, thereby protecting the bearings 15 I elaim- 1. In a1 gas producer, the combination with a wall inclosing a heating'chamber, a

rotatable ash pan below said chamber and arranged to support the fuel in said chamber, and means for imparting a rotative movement to the fuel in said chamber of a rotatable water cooled poker extending through said chamber, andl means` 'for rotating said poker.

2. In a gas producer, the combination with a stationary wall inclosing a heating chamber, a rotatable ash pan spaced below said chamber and arranged tosupport the fuel in said chamber, and means for rotating said, ash pan', of alined bearingsl in opposite sides of said wall', a rotatable water cooled poker journaled in said bearings and ex- 4tending through said chamber, and means for rotating said poker.

3. In a gas producer, the combination with a wall inclosing a heating chamber, a rotatable ash pan spacedbelow said chamber and arranged to support the fuel in said chamber, and means for' rotating said ash pan, of opposite bearingsin said wall with their axes in alinement, a rotatable bent water cooled pokeriournaled in said bearings, and means for revolving said oker.

5. In a gas producer, the combination with a heating chamber for the fuel, a rotating ash support, means for transmitting the rotation of said ash support to the yfue in said chamber, a cranked member eXtend-.
